The compounds of the formula I may be used as pure active substance or together with suitable carriers and- /or additives. Suitable carriers and additives can be solid or liquid and correspond to the substances conventionally used in formulation technique such, for example, as solvents dispersants, wetting agents, adhesives, thickeners, binders and/or fertilisers.

For application, the compounds of the formula I may be processed to dusts, emulsion concentrates, granules, dispersions, sprays, to solutions, or suspensions in the conventional formulation which is commonly employed in application terminology. Mention may also be made of cattle dips and spray races, in which aqueous preparations are used.

The agents according to the invention are manufactured in known manner by intimately mixing and/or grinding active substances of the formula I with the suitable carriers, optionally with the addition of dispersants or solvents which are inert towards the active substances. The active substances may be available and can be used in the following forms: Solid forms:

Dusts, tracking agents, granules, coated granules, impregnated granules and homogeneous granules. Liquid forms:

a. active substances which are dispersible in water:

wettable powders, pasts, emulsions;

b. solutions.

To manufacture solid forms (dusts, tracking agents), the active substances are mixed with solid carriers. Suitable carriers are, for example: kaolin, talcum, bolus, loess, chalk, limestone, ground limestone, attaclay, dolomite, diatomaceous earth, precipitated silica, alkaline earth silicates, sodium and potassium aluminium (DITHIA- silicates (feldspar and mica), calcium and magnesium,

sulphates, magnesium oxide, ground synthetic materials, fertilisers, for example ammonium sulphate, ammonium phosphate, ammonium nitrate, urea, ground vegetable products, such as corn meal, bark dust, sawdust, nutshell meal, cellulose powder, residues of plant extractions, activated charcoal etc. These substances can either be used alone or in admixture with one another.

Granules can be very easily manufactured by dissolving an active substance of the formula I in an organic solvent and applying the resulting solution to a granulated material, for example attapulgite, S10 granicalcium, bentonite etc. and then evaporating the solvent.

Polymer granules can also be manufactured by mixing the active substances of the formula I with polymerisable' compounds I (urea/forrnaldehyde; i'dic-yam diamide/formaldehyde, -mclaminc/formaldehyde -or H others), whereupon aimild polymerisation is carried out thatfdoesnot affect the active substa'rices and in the process .of which the granulation is carriedout during thegel form ation. It is more advantageous to impregnatefinished, porous polymer granules (urea/formaldei hyde, polyacrylonitrile, polyester or others) which have 'a specific surface area and'a favourable predeterminable adsorption/desorption ratio, with the active substances, for: example inthe form of their solutions (in a low boiling solventfand to remove the solvent. 'Pol'yhaving a bulk-.riehsity of 300 g/litre to 600 g/litre can also be manufactured with the aid of atomisers. The dusting can be carried out from aircraft over extensive areas ofcultures of useful plants." 7 I lt is also possible to obtaingranulesby compacting mer granules of this kind in the form of microgranules ylene glycols, dialkyl dilauryl ammonium chloride and Y and 350C. The solvents must be practically odorless,-

- not phytotoxic, inert to the active substances and not till carrier with the active substance and carriers and subsequently comminuting the product.

To these mixtures can also be added additives which readily inflammable.

Furthermore, the agents according to the invention can be applied in the form of solutions. For this purpose the active substance or several active substances of the general formula I are dissolved in suitable organic solvents, mixtures of solvents or in water. Aliphatic and aromatic hydrocarbons, chlorinated derivastabilize the active substance and/or non-ionic, anionic and cationic surface active substances, which for example improve the adhesion of the active ingredients on plants or parts of plants (adhesives and agglutinants);

and/or ensure a betterwettability (wetting agents) and dispersibility (dispersing agents), Examples 'of suitable adhesives are the following: olein/chalk mixture, cellulose derivates (methyl cellulose, carboxymethyl 'cellu-' lose), hydroxy ethyl glycol ethers of monoalkyl and dialkyl phenols having 5 to ethylene oxide radicals per molecule and 8 to 9 carbon atoms in the alkyl radical,

tives thereof, alkyl naphthalenes, and mineral oils alone or. mixed with each other, can be used as organic solvents.

The content of active substance in the above describedagents is between.,0.l to 95'percent, in which lignin sulphonic acids, their alkali metal'andalkaline earth metal. salts, polyethylene glycol 'ethers (carbowaxes), fatty alcohol polyethylene glycol ethers having 5 to 20 ethylene oxide radicals per molecule and 8 to 18 carbon atoms in the fatty alcoholmoiety, condensation products of ethylene oxide/propylene oxide, polyvinyl pyrrolidones, polyvinyl alcohols, condensation products of urea and fonnaldehyde, and also latex products. r

The water-dispersible concentrates of theactive substance, i.e. wettable powders, pastes and emulsifiablef concentrates, are agents which can be diluted with water to any concentration desired. They consist of ac -f tive substance-,carrier, optionally additives which stabilize the activesubstance, surface-activesubstanceand anti-foam agents and, optionally, solvents.

Wettable'powder and pastes are obtained by mixing and grinding the active substances with dispersing connection it should be mentioned that in the .case of application from aircraft or-someother suitable means of application, it is possible to use concentrations of up 1 to 99.5 percent or even pureactive substance.

. The active substances of the formula I can, for example, be forrnulated as follows:

-- The following substances are used to manufacture a) a 5 percent and b) a2 per md a) i 5 I parts of active substance 95 parts oftalcum h) 2 parts of active substance 1 part ofhighlydisperse silica 97 parts of talcum.

' Theactive'substances are mixed with the carriers and ground. I

agents and pulverulent carriers in suitable apparatus until homogeneity is' attained. Carriers are, for example, those mentioned for the solidforms of application.

ln some cases it is advantageous to use mixtures of different carriers. As dispersing agents there can be used, for example, condensation products of sulfonated. naphthalene and sulfonated naphthalene derivatives with formaldehyde, condensation products of naphthalene or naphthalene sulfonic acids with phenol and for-. maldehyde, as well as alkali, ammonium and'alkaline earth metal salts of lignin sulfonic acid, in addition, alkylarylsulfonates, alkali and alkaline earth metal salts of dibutyl naphthalene sulfonic acid, fatty alcohol sulfates such as salts of sulfated hexadecanols, heptadecanols. octadecanols, and salts of sulfated'fatty alcohol glycol ethers, the sodium salt of oleoyl ethionate,

the sodium salt of oleoyl methyl tauride, ditertiary acetglycol and c'etyl polyglycolether are then added; The thus obtained solution is sprayed onto kaolin, and the Granules I The following substances are usedto produce per 5 cent granules: 3 I
